1 = advertise the switch’s flow control capability via auto-
negotiation.
0 = will not advertise the switch’s flow control capability via
auto-negotiation.
1 = enable auto-negotiation on port 2
0 = disable auto-negotiation on port 2
1 = force port 2 to 100BT if P2ANEN = 0
0 = force port 2 to 10BT if P2ANEN = 0
1 = port 2 default to full duplex mode if P2ANEN = 1 and
auto-negotiation fails. Force port 2 in full duplex mode if
P2ANEN = 0.
0 = port 2 default to half duplex mode if P2ANEN = 1 and
auto-negotiation fails. Force port 2 in half duplex mode if
P2ANEN = 0.
1 = always enable (force) port 2 flow control feature
0 = port 2 flow control feature enable is determined by auto-
negotiation result.

Note: An external 1K pull-down is needed on this pin if it is
connected to a LED. The 1K resistor will not turn ON the
LED.
